NylokHD® / TuflokHD®

Prevailing Torque Locking Element

NylokHD^® / TuflokHD^® is a high performance self-locking nylon retention element permanently bonded onto the threads of a nut via a special application technique. NylokHD^® / TuflokHD^® will provide greater re-usability and reduced torque scatter. When the patch is engaged, it creates a wedging action between the nut and mating part, compressing the nylon and promoting tight metal-to-metal contact opposite the patch. This metal-to-metal contact provides a positive resistance to vibration and loosening. Since nylon has great memory characteristics, this locking element is reusable. NylokHD^® / TuflokHD^® can be applied to nuts of any style or plating. A wide range of nut sizes can be processed.
